Changelog

1. Changed all references of silver pieces to the generic "coins".
2. Changed Mage spellcasting. Instead of separate spell slots for each level, made it more like James West's B/X Wizard class with shared spell slots for all levels and a max spell level based on class level.
3. Added digging rates for shovels and pickaxes
4. Removed advantage / disadvantage rules since I don't reference them anywhere else in the text.
